WHEEL CLEANER FOR TRACTORS Filed Aug. 19. 1929 Jzwenivr Orr Z, fizdzo/ Patented June 7, 1932 UNITED STATES PATENT FF'I'CE ORR T-NICHOL, OF OMAHA, NEBRASKA, ASSIGNOR T NICHOL MANUFACTURING COM- PANY,.0F OMAHA, NEBRASKA, A CORPORATION OF NEBRASKA WHEEL CLEANER FOR TRAOTORS Application filed August 19, 1928.

The object of my invention is to provide a wheel cleaner of simple, durable and comparatively inexpensive construction, the cleaner being especially adapted for use in cleaning the wheels of tractors.

More particularly, it is my object to provide a wheel cleaner for a tractor such as the Farmall tractor and consisting of an L-shaped bracket adapted to have one of its ends connected with a bull gear cover plate of the tractor and its other end extending over the wheel of the tractor with a scraper blade vholder and scraper blade connected with r Mu such other end and extending downwardly toward the wheel of the tractor, such other end of the bracket being substantially spaced from the wheel to clear the lugs thereon and the scraper blade coacting with the wheel between such lugs, of which on the tractor under consideration, there are two rows along the sides of the rim with a central space between them.

Another object is to provide novel means for adjusting the scraper blade relative to the tractor wheel and consisting of a serrated curved face on the bracket, a similar face on the scraper blade holder, a clamping bolt and slot connection between these two and a clamping bolt and slot connection between the scraper blade holder and the scraper blade.

Still a further object is to provide a modified form of construction wherein the scraper blade may be adjusted relative to the bracket in another way.

With these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawing, in which:

Figure 1 is a plan view of a wheel of a tractor, showing the bull gear housing with my improved wheel cleaner attached thereto.

Figure 2 is a sectional View on the line 22 of Figure 1.

Figure 3 is a sectional view on the line 3-3 of Figure 1.

Serial No. 386,961.

F'gure l is a sectional view on the line l4: of Figure 2.

Figure 5 is a sectional view on the line 5-5 of Figure 3, and

Figure 6 is a view similar to Figure 3, showing a modified form of construction.

On the accompanying drawing, I have used the reference numeral 10 to indicate a portion of the rear drive shaft housing of a tractor. A bull gear casing 12 is secured to the housing 10 and includes a cover plate 1-1. The tractor wheel is indicated at 16 and two rows of spaced lugs 18 are secured thereto. The lugs 18 are ordinarily referred to as spade lugs.

My wheel cleaner consists of a bracket A having an upstanding leg 20 and an outstanding leg 22. The leg 20 is provided with a plurality of openings adapted to receive bolts 2%, whereby the bracket A may be secured to the cover plate 14 of the tractor. A tie rod or brace 26 extends from a bolt 28 on the bracket A to one of the bolts 30 which hold the housing 10 and the housing 12 together.

The outstanding leg 22 of the bracket A extends across the inside row of lugs 18, the leg 20 of the bracket A being sufiiciently long to allow clearance between the leg 22 and the lugs 18. A curved and serrated face 32- is formed on the outer end of the outstanding lug 22 of the bracket A and an opening 34 extends through such outer end. The opening 8% is elongated, as clearly shown. in Figure 2.

In connection with the bracket A, I provide a scraper blade holder B having a curved and serrated face 36 adapted to coact with the face 34 of the bracket A, as best shown in Figure 3. The scraper blade holder B is provided with a slot 38. A clamping bolt 40' extends through the slot 38 and the opening 34, whereby the curved faces of themcmbers A and B may be tightly clamped together.

A scraper blade 42 is attached to the holder B, a bolt 44 being provided for this purpose. A slot 46 is formed in the holder 13 so that the blade 42 may be adjusted up or down rela tive to the holder B.

In Figure it will be noted that the holder B has flanges 48 adapted to engage the side edges of the scraper blade 42 to prevent it from turning on the single clamping bolt 44:.

\ The serrations on the bracket A and holder B prevent pivotal movement of your holder relative to the bracket and thus it is necessary to provide but two clamping bolts and yet the members A, B and 42 are rigidly assem bled relative to each other and there is no possibility of pivotal movement between them.

Three distinct adjustments can be made. First, the holder B may be rocked relative to y the bracket A, due to the bolt and slot 3 connection; second, the scraper blade may be adjusted for centralizing it between the lugs 18 and the slot 34 and bolt connection; and third, the scraping edge of the blade 42 may y be adjusted relative to the rim of the wheel 16 by the slot 46 and bolt connection.

In Figure 6, I have illustrated a modified form of construction in which the leg 22 of the bracket A terminates in a round portion 50 which may be tubular to lighten the weight of the device if desired. The scraper blade holder B in this instance has a ringshaped upper end 52, which is split at 5A and has a pair of ears 56.

The holder B may be adjusted around the portion 50 of the leg 22 of the bracket A and secured in any adjusted position by the clamping bolt 58.

I have illustrated my scraper with but one wheel of a tractor, but it is obvious that a equivalents, which may be reasonably included within their scope.

I claim as my invention:

1. A wheel cleaner comprising a bracket having a segment shaped arm, a scraper blade having a curved face for coaction with the curved face thereof and a clamping bolt through said arm and blade, said curved faces having slots through them for the clamping bolt, said slots being arranged at right angles to each other.

2. A wheel cleaner comprising a bracket having a segment shaped arm, a scraper blade having a curved face for coaction with the curved face thereof and a clamping bolt through said arm and blade and through the curved faces thereof, one of said curved faces having a slot for the clamping bolt to extend through. V

3. A wheel cleaner comprising a bracket having a segment shaped arm, a scraper nsensvs blade havin a curved face for coaction with the curved face thereof and a clamping bolt through said arm and blade and through the curved faces thereof, one of said curved faces having a slot through which the clampin bolt extends, said curved faces being serrated at right angles to their curvature.

4. A wheel cleaner comprising a bracket having a segment shaped arm, a channel shaped scraper blade holder having a curved face for coaction with the curved face of said arm, a bolt for clamping said faces together and a flat scraper blade having a slot and a single clamping bolt connection with said channel shaped scraper blade holder, said flat scraper blade fitting between the flanges of said channel shaped scraper blade holder.
